IMPROVEMENT IN ATMIZERS.

Specification forming part of Letters Patent No. 160,802, dated March16, 1875; application filed February 3, 1875.

To all whom it may concern l Be it known that I, GHAuLEs WERD, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented a'n Improved Atomizer, of which the following is aspecification: 1

My invention relates to that class of atomizers, in which the current ofair for atomizing duid contained in a vessel or bottle is produced by anelastic bulb, and is an improvement on Patent Nall-7,651.

My invention consists in the arrangement, with relation to the bottle orliquid-containing vessel, of the air or atomizing tube andliquiddischarging tube, so that the atomizing-tube, when in operationand held in substantially a vertical position, or slightly inclined froma vertical position in the direction of the bulb, will direct a currentor blast of air across the open end of the liquid-discharging nozzle,which is made to slightly overhang the atomizing-tube, and remove theliquid suspended at the discharging end of the duid-tube; also, in thearrangement of the air or atomizing and liquid tubes within a tuberising from the bottle-stopper, substantially as hereinafter described;also, in the combination, with aliquid-containing vessel and elasticbulb, arranged as herein shown and described, of a pipe rising from thevessel, and projecting forward to any desired distance, and having atits end an atomizing-pipe and an overhanging huid-discharging pipe,whereby it is possible to introduce the mouth of the atomizer and liquidpipe to any desired position for medical purposes, as in the mouth ornostrils.

Figure l is a side view of an atomizer provided with my improvements,and Fig. 2 is an enlarged sectional view of a part of the same, thelower portions being broken away.

In the drawing, a represents the liquid-containing bottle or vessel; b,the elastic bulb for producing a blast or current of air, both ofordinary construction. A neck-piece, g, is fitted in the end of bulb b,and is connected by connecting-pipe t with the bottle-stopper f,preferably having an outer `lining of india-rubber. The end h of theliquid-tube d descends nearly to the bottom of the bottle, and iscurved, as shown7 so that the bottle may remain in a vertical position,or be somewhat tipped toward the bulb b, and allow the bottom of thetube to remain in the liquid, and it will be noticed that the tube willremain in the liquid until the bottle is turned toward the bulb intoalmost a horizontal position, and yet the fluid or liquid will not runout of its own accord until the bottle is turned to a horizontalposition. Rising from the stopper is aninclosingtube, c, bent at c1, andprojecting forward substantiallyin a horizontal position, suchhorizontal part being designated by the letter o2, and it may be of anydesired length. lVithin the inclosing-tube c is arranged the liquid-tube d', its discharging-nozzle d projecting beyond the inclosing-tube o,and being bent downward so as to come opposite or nearly so to the openend of the atomizing-tube e, which is located immediately below theliquid-tube, substantially as shown, and yet within the inclosing-tubec. The tubes c d e are united at the end of o, by means of solder orotherwise, so as to furnish a perfectly tight joint. By arranging theend d and atomizing-pipe e as shown, it will be noticed that the liquidcoming from the discharging end d will be suspended while it is acted onby the blast of air issuing from the atomizing-tube e, and the air willcompletely and easily detach substantially all the liquid; and there is,it will be also 11oticed, no opportunity for any liquid to settle downor flow or run back on the liquid-discharging pipe, and there is noopportunity for the liquid to gum or foul on the liquid-dischargingpipe, or at the mouth of the atomizingtube c; and as the suspended dropsof liquid are easily and eifectually removed by the atomizing-tube e,arranged just below its overhanging end, it follows that there is noopportunity for the liquid to run back and down on the pipe leading tothe bottle. This fouli g of the bottle and stopper is a very seriousevil in atomizers as heretofore constructed, and by this my arrangementof parts this evil is avoided. The liquid used is often of a verydisagreeable nature. These atomizers are ot'- ten used for treatment ofvarious diseases, wherein it is desirable to apply medicinal liquid orWash to interior portions of the person, and by my new arrangement ofparts the horizontal part c2 need only to be extended or curved in anydesired shape, the small over- FFTG.

hanging discharge-pipe and the atomizingtube projecting from the endworking equally Well no matter what is the length of the pipe c. Thereis an air-space, n, between the outside of liquid-tube d andinclosing-tube c. The atomiZing-tube e communicates with this space, andair forced from the bulb b,through the connecting-pipe fi, passesthrough the space n, and issues from the atomizing-tube e.

The operation of the atomizing-tube to form a vacuum in the tube d', andallow the liquid to rise, is too well understood to need furtherdescription.

My invention, as to the location of' the discharging-outlet of theliquid-tube with relation to the atomizing-tube, may be carried out byarranging the atomizing-tube e as a separate pipe under the, liquid-tubed', as in Fig. 3.

The bottle when in use will almost always be kept in a verticalposition, or nearly so, as shown'in Fig. l. The liquid is discharged asa spray substantially at right angles to the length of the bottle, andby an atomizing-tube arranged beneath the overhanging end of theliquid-tube. The outlet of the huid-tube is bent sufciently below thatportion of the tube just back of it, that when the bottle is in avertical position a drop of uid at the end oi' the tube, if not blownoff', would not run back on the tube and down to the bottle. The extremepoint of the liquid-tube d is depressed or turned down so as to overhangthe opening in the atomizing-tube. This extreme point I designate asdepressed point x, and it will be seen that liquid cannot run back upand Voutside of it.

Having described my inventionI claim- 1. The combination, with thebottle and a uid-tube rising therefrom, and bent or curved substantiallyas described, of an atomizingtube arranged below the overhangingliquidtube, and adapted to discharge the fluid as a spray, in adirection inclined to the length of the bottle, or the main portion ofthe tube, substantially as described.

2. The combination, with the bottle, of an atomizer of a Huid-tubehaving its extreme or outlet end w depressed with relation to theremaining portion of the tube, substantially as described, to preventthe ow of the liquid along the outer side of the tube to the bottle,substantially as described.

3. The combination, with the bottle-stopper and the in closing tuberising therefrom, of the liquid-tube and atomizing-tube, arranged insidethe inclosing tube, but projecting from it at top, substantially asshown and described.

4. ln combination, the neel; g, connectingpipe 11, stopper f, inclosingtube 0, liquid-tube, and atomizin g tube e, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
